Ocean Giants (Actual Size)

Just how big is a giant squid? Not quite as big, perhaps, as you might think. This fabulous new graphic from the Deep Sea News crew and several other scientists represents *a lot* of research to find out the true largest sizes of 25 ocean creatures of giant repute.

Just how big is a giant squid? Not quite as big, perhaps, as you might think. This fabulous new graphic from the Deep Sea News crew and several other scientists represents *a lot* of research to find out the true largest sizes of 25 ocean creatures of giant repute. It appeared today to accompany an article detailing the data that went into it in the open-access journal PeerJ.

To collect their data, they consulted museum specimens, talked to curators, and even checked eBay for specimens for sale. The squid itself has long been stated on the internet to reach 60 feet in length. But thanks to McClain et al.'s efforts, we now know the largest reputable recorded size is closer to about 40 feet. Still huge. Just not as huge.

What really jumps out at me here though is *not * the somewhat smaller-than-expected size of the giant squid. It's the HUGE-ASS giant octopus! Dear lord! They can reach 32 feet across?? I had no idea. That's big enough to Jules-Verne a mini-sub, and *definitely* big enough to swallow me. Although if you've ever met me, you know I'm pretty snack-size for a variety of predatory creatures.

That the lion's mane jellyfish can reach blue-whale length is also rather breathtaking and unexpected.

It’s Time to Stand Up for Science

If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.

I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.

If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.

In return, you get essential news, captivating podcasts, brilliant infographics, can't-miss newsletters, must-watch videos, challenging games, and the science world's best writing and reporting. You can even gift someone a subscription.

There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.

Thank you,

David M. Ewalt, Editor in Chief, Scientific American
